touching the void

given the fact that i have been working with java for almost 8 years now, i am always surprised about language functionality that i have never met before — my latest encounter: java.lang.Void (since JDK1.1).

the importance of this class has dramatically increased by the introduction of generics, and you probably want to use it along the lines of:

Callable<Void> c = new Callable<Void>() { public Void call() { // nothing to return return null; } };
